Slate - Deprecating float GetRelativeLayoutScale(const FSlotBase& Child, float LayoutScaleMultiplier), Long Live float GetRelativeLayoutScale(const int32 ChildIndex, float LayoutScaleMultiplier), you must also set bHasRelativeLayoutScale to true in your constructor for your SWidget if you need this function called. This removes 2 virtual calls from almost every widget's prepass, and only now requires 1 for every widget that needs to implement GetRelativeLayoutScale, which very few actually do.
